Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with specific embodiments.

[0018] 1. Amide type lubricating oil biodegradation accelerator, its chemical formula is C 2 0H 37 NO 3 , the structural formula is:

[0019] .

[0020] 2. Synthesis method

[0021] A preparation method of an amide type lubricating oil biodegradation accelerator, specifically comprising the following steps:

[0022] 1) Dissolve a certain amount of sodium hydroxide in a quantitative mixed solvent, then add a certain amount of amino acid and stir to dissolve in a three-necked flask;

[0023] Among them, sodium hydroxide is 0.1mol / L; the mixed solvent is composed of water and tetrahydrofuran, and its volume ratio is 1:3; the molar ratio of amino acid to sodium hydroxide is 1:1;

[0024] 2) Drop 68g of oleic acid chloride at a certain temperature, and dropwise add sodium hydroxide solution at the same time to maintain the pH value of the system at 10-11; afte...

Abstract

The invention provides an amide-type lubricating oil biodegradation accelerator and a preparation method thereof, the chemical formula of which is C20H37NO3. It has a good biodegradation promoting effect on lubricating oil. The lubricating oil biodegradation accelerator has stable properties, is not easy to be hydrolyzed, has excellent tribological properties, has good antirust and antibacterial effects, and has an obvious effect on promoting the biodegradation of lubricating oil. The method for preparing the lubricating oil biodegradation accelerator of the present invention has the advantages of readily available raw materials, mild conditions, simple operation, low requirement on equipment, easy removal of by-products and easy realization of industrialized production. Moreover, the raw materials for preparing the lubricating oil biodegradation accelerator have a wide range of sources, and the price is relatively cheap.

Description

technical field [0001] The invention relates to the synthesis of a lubricating oil biodegradation accelerator and its synthesis method, and the technical fields of biodegradation. Background technique [0002] Mineral lubricants enter the environment due to leakage, splashing, evaporation, residues in packaging supplies, improper recycling, etc. during use, storage, and transportation, which will cause direct pollution to the environment, especially to aquatic plants and animals. affect, or even destroy, the ecological balance. Although the environmental pollution caused by lubricants is not particularly serious compared with many other chemical products, it still has a non-negligible impact on the environment due to its wide application, small amount but wide expansion area. According to statistics, currently about 5-10 million tons of oil-based chemicals enter the biosphere every year in the world. Even in countries with a high lubricant recycling rate (>60%), 4%-10% o...
